Fresnel formula can perfectly explain the variation of the light in the two kinds of uniform and transparent media interface reflection and refraction, amplitude, phase, polarization state, light energy. This article first describes the course of people39。s understanding of the nature of light, and the tremendous contribution of the Fresnel optical development and use of Maxwell39。s electromagic theory of boundary value relations export Fresnel formula to the interpretation of the electromagic nature of light. And the electric vector of the vector deposition and subvectorforward provisions and vibration characteristics, detailed discussion and analysis of the variation of the formula of the other drawings to illustrate to enhance intuitive, and the use to explain, such as halfwave loss, cloth Confucian Manchester law, total internal reflection, optical phenomena. Finally, in the field of optics in particular, is widely used in the polarization of light, thin film optics, electronics and information optics, made a detailed discussion and research. Key words: Fresnel formula; Phase。polarization。Amplitude。 Application 畢業(yè)設(shè)計(jì)(論文) III 目 錄 摘要 .............................................................................................................................................
